ATLANT Decentralized Exchange (ADEX) contracts

Exchange matching engine implemented as a smart contract written in Solidity language (Ethereum).

Order matching supported, as opposed to many existing exchange contracts (e.g. EtherDelta). Ethereum ERC20 tokens traded versus Ether.

• Order matching
• Any ERC20 token support
• Exchange decentralization
• Funds inaccessible for 3rd parties
• Optimized performance
• Reduced gas consumption

• Base currency: ERC20 token (any)
• Quote currency: ETH

Any ERC20 Ethereum token may be deposited to this exchange contract and subsequently traded versus Ether.

This includes a series of at least two transactions: a deposit transaction (ETH or ERC20 token) and an exchange transaction (providing amount & price). Token exchange is conducted by the contract automatically.

This contract references the rbt-solidity library, providing RB tree data structure for the order book implementation (orders sorted by price).

• Order search O(log n)
• Order insertion O(log n)
• Order removal O(log n)
